Detailed explanation-1: -Resistive touch screens have two layers that are either made of PET film or glass/ polycarbonate plastic. Glass usually makes up the bottom layer, and glass or film makes up the upper layer. Depending on the application, alternative pairings such as glass/glass and film/film are also used.
Detailed explanation-2: -Surface acoustic wave (SAW) technology uses ultrasonic waves that pass over the touchscreen panel. When the panel is touched, a portion of the wave is absorbed. The change in ultrasonic waves is processed by the controller to determine the position of the touch event.
Detailed explanation-3: -The upper layer of a resistive touchscreen device is made of transparent glass or plastic with an electrically conductive coating, such as indium tin oxide (ITO).
Detailed explanation-4: -In simple terms, a Resistive Touch Screen is a touch-sensitive computer display that responds by applying pressure. It’s made from two resistive-coated transparent sheets that are separated by a small air gap. When contact is made to the surface of the touchscreen, these two sheets are pressed together.
